nnnn TWIST FLYJEE SPINNING EAGHINE Application filed April 29, 1931,Serial No.

In the American patent application filed on the 3rd April, 1930, underSerial No, 440,999, a double twist dyer spinning machine has beendescribed which efi'ects certain improvements over those of the doubletwist type in which the thread unwinds from a bobbin situated inside thehall formed by the rotation of this thread, and which is essentiallycharacterized by the whole control w mechanism both of the winding drumcarry mg the spun thread, as well as of the thread guide, being looselymounted on the pirn inside the bell formed by the rotation of the threaddrawn from'the outside and, during operation, wound on the inside of themachine, and losing in equilibrium by gravity, by arran ing its centreof gravity below the axis of the said pirn.

The present invention has for its object to make certain modificationsin this type of machine principally as regards the mechcausing thetraversing movement of thread guide to distribute the thread over thehobhin situated inside the hall formed rotation of the said thread, andits inethod control;

It refers also to a general arrangement of the spindles on the frame ofa splnning ma- According to the somewhat complicated device of thethread guide by means of a cam, a rocking lever forked at its outer endand a slide, such as is described in the patent specification abovereferred to, there is produced an excessive encumbrance in view of thesmall space available, and after a certain period of usage the playbetween the difierent membersincrcases and leads to defective operationof the thread guide.

40 Furthermore, as the control cam is always driven at the same speed bythe pin it follows that the traversing movement of the thread guideremains constant whatever may be the speed of the roller, Alexandre bobubin, cop or the like which receives the twisted thread. The traversingmovement thus varies according to the speed of the bobbin or the like.

The present invention, which has for its object principally to obviatethese varlous 533,671,22116 in France Zinne 20, 1930.

of a fork or yoke journalled in a slide to which is attached an armcarrying the thread guide through which'passes the thread to bedistributed over the receiver bobbin.

' 2. The rotation of this double threaded screw and thus the speed ofdisplacement of the traverse is controlled hy the intermediary, ifnecessary, of a suitable transmission by gearing or otherwise, or by thereceiving bobbin of the spun thread, in such manner that the traversingmovement remains constant whatever may be the speed of rotation of thisbobbin.

3. 0n its exit from the pine, the thread is supported on a fixed part,for example, a bead fixed onthe casing, in order to prevent its contactwith the end of the said pirn which is in rotation, and consequently toavoid friction causing the fiatting or glazing of the thread.

4. The control of the sliding changespeed gear is, in view of itsgreater convenience in manipulation, fitted to the upper part of thecasing.

- As regards the general arrangement of the fiyer spindles on the samespinning frame, the principal characteristics are the follow in Y lst.All the pirns of one spinning frame are arranged on one or moredifierent stages and staggered in each stage, that is to say,alternately on the right or on the left of the frame, the driving of allthese pirns being eflected by means of a single tensioned belt, the runsof which, in the case of two or more stages, are in the same verticalplane,

and which passes. over and under the pirns of each stage.

2nd. Each pirn is provided both for un- 9 winding from. a rotary spoolas also for untwisting from a stationary spool, with a system ofautomatic compensation and braking currently used on certain other t pesof tex- 1 tile machinery such as cop win ers, with a view to regulatingby the tension of the thread, the dimension of the ball.

The invention also has in view certain other detail arrangements whichwill be hereinafter fully set forth, and it has still more particularlyin view, under the title of novel industrial products, double twistspinning flyer spindles comprising wholly or partially the applicationof the above-mentioned devices.

The invention will be readily understood by reference to the followingdescription and the annexed drawings, which description and drawings aregiven by way of example only.

Figures 1 and 2 are two side elevations partly in section showing theflyer spindle respectively from the side, on which the receiving bobbinis driven, and on the side of the traverse drive.

Figure 3 is a plan view in partial section.

Figures 4 and5 are two Views of the flyer spindle from the-back (coverremoved) ,and from the front respectively.

Figures 6 and 7 show in side and front elevation respectively the methodof fitting up the flyer spindles and their respective ar-' rangements insta es.

s in the prior patent the fixed casing 1 the case of two superposedcontaining the various transmission members is suspended by theintermediary of ball bearings 2 locatedat the end of the pirn 3 carryinga worm 4 continuously meshing with a gear 5 keyed on the shaft 6 of thecone or step gear 7. y

The shaft 8 which carries the sliding pinion 9, is fixed thereto in thesense of rotation by means of key and feather way connection 10 whichnevertheless allows the said pinion to move longitudinally of the shaft.

This shaft has fixed at its extremity another pinion 24 constantly, inniesh with a gear 11, and is supported by a pair of elbow levers 12arranged in thQfOlin of a cage adapted, under' the action of ,theexternal control 13, to pivot about the axis 14 of the pinion 11. Areturn spring 15 tends to force this cage continuously in the directionof the arrow (Figure 1) so as to keep the sliding pinion 9 in mesh withthe cone gear 7.

From the gear 11 movement is transmitted to the'felt cylinder 16 drivingby friction contact the bobbin 17 carried at the end of the arm 18,hinged at 19, by means of a gear train 20, 21, 22 of which the gears 21and 22, may be interchanged with a view to increasin the number 0 speedsgiven by the cone 7. e displacement of'the sliding pinion 9 on its axis8 is effected by means of an external lmob 13 which is adapted to bemoved in front of a graduated scale 28 and which is integral with a bentrod 23 fixed to a lining 25 concentric with the sleeve 26 of the saidsliding gear 9 and prevented from moving longitudinally of said sleeveby means of a stop 27 'Thus flattening or glazing ery two cross threadsconnected together at the extremities of the said screw as at 36, toform reversing cams.

In this thread slides a fork or yoke 37 carried by a trunnion 38engaging in a slide block 39 guided on a rod 40 and fixed to a clutch 41passing through a slot 42 in the casing 1. An arm 44 which is hinged at43 to the clutch member 41 carries atits outer end the thread tide 45into which the thread 46 passes efore being wound on to the bobbin 17.

The aperture 47 made in the casing 1 opposite the exit of the pirn 3 isprovided with a stationary bead 48 arranged in the axis of the saidpirn, the diameter of the hole in said bead being smaller than that ofthe channel 49 into which the thread 46 passes. of the thread by contactwith the edge of the rotating pirn is prevented.

A semi-circular protector 54 arranged above the worm 4 partially stopsoil thrown upwardly by said worm.

As in the prior application the thread passes, in view of its thrown orballoon formation and before its introduction into the pirn, through aguide 50 carried by a disc 51 rotating with the pirn.

A ring 52 situated in front of the flyer spindle and adapted to rockaround the axis 53, prevents the thread which is to form the ball, atthe moment of starting, coming into contact with the casing or with anyof the mechanism associated therewith.

A double set of ball bearings 56, each supporting a pirn 3, are fixed intwo stages on superposed cross pieces 57 and 58 of a single machineframe and staggered on each of 1.

these cross pieces, so that the flyer spindles are situated successivelyto the right and to stage to the left of the frame, and vice versa 2(Figure 7).

On the 'other hand, in each stage the axes of thepirns of the flyerspindles which are situated on the same side of the frame are slightlystaggered with relation to those of the pirns of the flyer spindles ofthe same stage situated on the other side of the frame.

lit is thus possible to drive all the spindles of the two stages of oneframe by means of a single belt 59 passed alternately above and belowthe pines between the spans of the double ball bearings 56 and stretchedby means of an idler pulley 60.

Each flyer spindle is provided with an individual stopping deviceconsisting of a brake block 79 (Figure 6) applied against the pirn 3 bymeans of a rod 61 supported on an eccentric 62, the rotation of which iscontrolled by the lever 63.

In the case when the thread supply to the spindle is effected byunwinding from rotary 67 wound round an axis 68 arranged at the top ofthe corresponding bracket of the said bobbin, the other end 69 of saidwire engaging in one of a series of notches in a-toothed sector 70 fixedon the said axis 68.

The wire 67 is, on the other hand, connected by a rod 71 to a resilientbrake blade 72, said rod being guided at its lower end in the bracketbelow the axis of the-bobbin 64, the action of the brake blade on a drum73 secured to the bobbin being determined by the setting of the end 69of the wire 67 within the notches of the sector 70.

Gontrar to what is shown on the drawing aligned with said the thread iside pirn to the t read the aperture in sai pirn and through which on itspassa e from the uide, the iameter of f bead being less than that of thepirn, a yoke connected to the thread guide, a double cross-threadedscrew engaging with said yoke, the threads of said screw being connectedat their ends to form reversing grooves for the yoke, and a casingpivotally mounted on said spindle or pirn and maintained in constantequilibrium by gravity, said casing housing the driving gear for thebobbin, guide and screw.

2. In a double twist flyer spinning machine, a horizontal spindle orpirn, a winding bobbin, a gear train interposed between said spindle andbobbin, one of said gears being slidably mounted to engage with one of aplurality of stepped intermediate gears, a traversin thread guide and ayoke connected to sand guide, a double cross-threaded screw engagln withsaid yoke, the threads of said screw eing connected at their ends' toform reversing grooves for the yoke, a casing pivotally mounted on saids indle and maintained in constant equili mum by ravity, said casinghousing the driving gear or the bobbin, guide and screw, and a controllever for the sliding gear, said control lever terminating above theupper part of the casing. p In witness whereof I aflix my signature.

ALBERT (Figure 7 and this simpl .to increase its clearness, the'twoantennae 6 of one bracket, which antennae are .situated respectively tothe right and to the left of the frame, should be situated both in thesame vertical plane which also coincides with that of the flyer spindleswhich they have to supply, and which, as above mentioned, are themselvessituated back to back in different stages, or, in other words, in thesame vertical plane.

On leaving the antennae, the thread 46 passes, before arriving at itsflyer spindle, into a guide 74 carriedon an arm 75 fixed on the frame.

Moreover, in the case of untwisting, the bobbins 77 ma also occupy theposition shown in dotte line in Figure 6, at the top part of the frame.

It will be understood, as a result of the foregoing description, thatthe invention is in no way limited to the single method of carryingit-out or to that of its different parts; it covers, on the contrary,all variations of embodiment, comprising wholly or in part theapplication of. such devices.

at I claim and desire to secure by Letchine, a horizontal spindle ingbobbin driven by said spin e, a traversing thread guide,

a stationary bead axially
